Number 29. Please help?

Answer:
A congruence transformation is something that keeps its shape and form of another shape or form, a transformation that doesn't change the size or shape of an object. We refer to three main types of congruence transformations, and those are reflections known as flips), rotations known as turns), and translations known as slides
Slide (Translation) Every point of an object is moved the same distance and in the same direction. A slide is also called a translation. We know it is a slide as it is a motion in geometry in which an object is moved along a straight line without turning or changing the size or shape.
The shape/object created during a transformation is called an image. A roller coaster is an example of a lesser known geometry translation (slide). During a translation, the object has remained aligned in the same direction and has moved, or slid, to another spot.
Step-by-step explanation:
The reasoning is wrong if they speak of text, or refer to slide text entering of a box. This box does not slide etc.. then it is not the correct meaning.
